摘　　要：纵波勘探在浅部60m以内属于勘探盲区,为了解决这一难题,了解活断层在浅部的延伸情况,对横波地震反射法在活动断裂探测中的应用进行了系统分析和总结,并利用该方法对苏北地区的活动断裂进行了探测。与纵波反射法相比,横波反射法精准的确定了活断层在浅部的空间位置。P-wave exploration is a blind area within 60m in the shallow part.For solving this problem and understanding the extension of active fault in the shallow part,the application of shear wave seismic reflection method in active fault detection is systematically analyzed and summarized,and the active faults in Northern Jiangsu Province are detected by this method.Compared with longitudinal wave reflection method,shear wave reflection method accurately determines the spatial position of active fault in shallow area.
